What is the maximum efficiency of an engine operating between 500 K and 300 K?
A) 20%
B) 30%
C) 40%
D) 50%
E) 60%

Question

Quizplus · Accepted Answer

The maximum efficiency of an engine operating between 500 K and 300 K can be calculated using the Carnot efficiency formula, which is given by:
Efficiency = 1 - (T_low / T_high)
where T_low is the temperature of the cold reservoir (in Kelvin) and T_high is the temperature of the hot reservoir (in Kelvin).
Substituting the given values, we get:
Efficiency = 1 - (300 / 500) = 1 - 0.6 = 0.4 or 40%
Therefore, the best choice is C, which corresponds to an efficiency of 40%.
